PIXEL and Cosmo Hunters: INAF New Research Frontiers for Game-based Astronomy Education

Games and playful activities have emerged as powerful tools for public engagement and education, particularly in nurturing the learning of new generations. The INAF National Working Group on Game and Creative Learning has dedicated years to developing tailored games for astrophysics education. In this presentation, we examine the research conducted on two exemplary cases: PIXEL - Picture (of) the Universe and Cosmo Hunters, both meticulously crafted board games designed to engage learners of varying ages.

Manuela Lippi

Something about me and something about 12P

I will present myself and my professional career, and I will introduce the ALMA large program on the comet 12P, showing (hopefully) some preliminary results.

A glance at Faraday tomography: an exciting technique to explore the magnetized Galaxy

I will take the chance to present myself and introduce you to Faraday tomography. This is a new technique that promises to give an additional perspective in the study of Galactic magnetic fields based on broad-band meter-wavelength polarization data from radio facilities such as LOFAR today and SKA in the coming future.

Gaia-NIR: the next generation astrometric mission

GaiaNIR is a new space mission based on the Gaia principles, but working in the near infrared that has been proposed for the ESA call Voyage 2050 and was recommended by the Senior committee. In this brief talk I will describe the goals of this mission, outline the path towards the launch that is expected around the 2045 and discuss the potential involvement of our institute in this project.

 

Georgios Kyriakou

Revisiting my research experience in INAF-OAA

In this talk, I will present a short outline of my research activities as a research fellow at Arcetri for the past 3 years. These are related to preparatory simulation work for the Square Kilometer Array (SKA) Low-frequency telescope, as well as some other collaborations. Finally, I will also mention the tools and expertise developed in radio-simulation software, which will be made available to any colleague interested in their use.

How to trust machine learning algorithms? The example of a neural network to determine stellar parameters and their uncertainties from high-resolution spectroscopy

Next generation instruments are prompting a revolutionary surge in collecting a wide variety of data. The significant shift in data volume requires the development of new codes to preprocess the huge flux of data collected every night and to analyse it in a quick but reliable manner. In this talk, I will briefly introduce OssicoNN, a neural network expressly devised to address new challenges associated with the determination of stellar parameters and their uncertainties.

Giant Exoplanets: a global approach to their lives

In this presentation I will show how combining different methods for the detection and characterisation of exoplanets (from direct imaging, to gravitational waves), can help us constrain the formation and long-term evolution of planetary systems.

Probing Galactic cosmic rays via gamma-ray observations

Cosmic rays are charged high-energetic particles that permeate the Galaxy and arrive at Earth from any direction. The accumulation and effective mixture of these relativistic particles during their propagation through the interstellar magnetic fields results in the formation of the so-called "sea" of galactic CRs. As a consequence, tracing the origin of these particles cannot be done by direct measurements and should rely on observations of secondary neutral particles, such as gamma rays and neutrinos, which travel unaffected from the cosmic-ray interaction regions to us. I will present myself and give an overview of the investigation that we performed using gamma-ray data on the properties of Galactic cosmic rays, providing some examples on observed accelerators, detected runaway particles and on molecular clouds, which are considered the main CR 'barometer' of the Galaxy.

Welcoming high-frequency VLBI in Korea and Italy

In anticipation of installation of the new tri-band high-frequency receivers on the Italian radio telescopes, I participated in the installation and first light test of such receivers at the new Pyeongchang station of the Korean VLBI network KVN. In this talk, I will give a quick introduction to the new KVN station, new receivers, and the bright future of high-frequency VLBI.

Report from WRC23: the future of the radio spectrum

In this presentation, I share my experience as a CRAF delegate at "WRC23" in Dubai, December 2023, where the future utilization of the radio spectrum was outlined. This conference is a significant meeting point for global administrations and major industry players, all working to secure their share of spectrum usage.
I plan to offer a different viewpoint on radio astronomy, depicting it as a service that depends on spectrum usage. The presentation will cover a summary of our accomplishments in Dubai and detail the initiatives we intend to undertake for the protection and progress of radio astronomy in the upcoming years.

Constraining Quasar Feedback Models with the Atacama Large Millimeter Array

The thermal Sunyaev-Zeldovich (SZ) effect serves as a direct potential probe of the energetic outflows from quasars that are responsible for heating the intergalactic medium. In this presentation, I will briefly explain our work on characterisation of SZ effect arising from different quasar feedback modes using the GIZMO meshless finite mass hydrodynamic cosmological simulation called SIMBA (Dave et al. 2019). Also, from these theoretical simulations, we perform mock observations of the Atacama Large Millimeter Array (ALMA) in four bands (320 GHz, 135 GHZ, 100 GHz and 42 GHz) to characterize the feasibility of direct detection of the quasar SZ signal.

The nine lives of the OTT, or optical measurements in Test Tower for the ELT adaptive mirror

In this talk I will give an overview of our work in the OTT, the opto-mechanical facility for the verification of the ELT adaptive mirror M4. The wheel of fate tried strongly to make our lives harder, including a hammer falling on the parabolic mirror, the haunted polishing machine, a ghost astigmatic shape, a rough hologram and a busy highway 3 km away; yet, we calibrated the OTT to 3 nanometers.
We completed the review with ESO in November and we eagerly waiting for the arrival of M4.

Astrobigné Organising Committee

Present and future of the Astrobigné meetings

In this last Astrobigné of the year, we will discuss the results of the survey we invited you to take at the beginning of the season, and present the (additional) changes to the format that will become fully effective in January. This will also be an opportunity of brainstorming to define the future of Astrobigné in the social life of the Arcetri community.

Bruno Canto (OAA + UFRN, Brazil)

Astronomical Connection: An Authentic View of My Scientific Career

In this short seminar, I will share insights into my scientific career, addressing its origins and my interests, while exploring what led me to O.A. Arcetri. I will emphasize how this opportunity marks a significant new chapter in my scientific journey, providing innovative perspectives to contribute across different domains of astrophysics.

What I learned about the ERC granting process

I will briefly present the ERC granting scheme, with its written and unwritten rules. I will then describe my own experience with this type of funds, and the lessons I learned from experience rather than from study. I will place the accent on a few aspects that I believe are important to keep in mind for new applicants. I hope I will be able to dispel some of the myths surrounding this type of grants, encouraging more researchers to apply, after realistically evaluating their success chances in advance. I will also discuss about the non-deterministic nature of the process.

Il programma delle visite diurne e serali e altre attività di didattica dell'OAA

Presenteremo i risultati e il report delle attività 22-23, con particolare focus sull'attività ordinaria di visite e sulle criticità emerse. Illustreremo le previsioni per il prossimo anno e discuteremo di alcune altri progetti di D&D: per tutte queste attività il contributo di tutte e tutti i ricercatori dell'Osservatorio è sempre molto fondamentale.

Come disfarsi di uno strumento scientifico pdf

Ovvero come l'invio di un prototipo costato anni di fatica presenta insospettabili problemi sia di carattere tecnico che burocratico. Commenteremo brevemente come l'invio del prototipo di sensore di fronte d'onda a piramide per il GMT ha messo in evidenza alcune criticità insite nelle operazioni di spedizioni di strumentazione scientifica.
